He said... Let's go out and have some fun tonight.
She said...Okay, but if you get home before I do, leave the hallway light on.

Celeste Holm (a.k.a Ado Annie) sings:

"...With you, it's all er nuthin' -
All fer you, and nuthin' fer me
But if a gal is wise
She's gotta realize
That men like you are wild and free.

So I ain't gonna fuss, ain't gonna frown,
Have yer fun, go out on the town,
Stay out late and don't come home till three,

And go right off to sleep if yer sleepy,
Don't be waitin' up
Fer
Me !"
